The National Weather Service in Mt. Holly is forecasting a prolonged period of dangerously hot and humid weather across the region during the second half of this week and continuing through the July 4 holiday weekend.

Dangerous heat is expected to persist from July 1 — 4.

Lehigh County encourages all residents to take precautions to protect themselves, their families, neighbors, and pets from heat-related illnesses.

Be Informed

•Most heat-related illnesses occur when a person is exposed to excessive heat or overexerts themselves. Infants and young children, adults age 65 and older, people with chronic medical conditions, and those who work or exercise outdoors are at greater risk.

•Monitor local weather forecasts and pay close attention to heat watches, advisories, and warnings through television, radio, or trusted online sources.

•Learn to recognize the signs and symptoms of heat exhaustion and heat stroke.

•Never leave children or pets unattended in a parked vehicle, even for a short period.

Stay Cool

•Spend as much time as possible in air-conditioned buildings.

•If you must be outdoors, limit strenuous activities to the early morning or evening hours and take frequent breaks in the shade.

•Wear lightweight, light-colored, loose-fitting clothing, along with a wide-brimmed hat, sunglasses, and sunscreen (SPF 15 or higher).

•Check on older adults, family members, neighbors, and anyone who may be vulnerable to extreme heat.

•Keep your home cooler by closing blinds, curtains, or shades during the hottest part of the day. Window reflectors can also help reduce indoor heat.

•If your home is not air-conditioned, consider visiting a friend or neighbor, a local library, shopping mall, or another air-conditioned public building.

Stay Hydrated

•Drink plenty of water throughout the day. Do not wait until you feel thirsty to hydrate.

•Avoid sugary, caffeinated, and alcoholic beverages, which can contribute to dehydration.

Heat-related illnesses can develop quickly but are largely preventable.

By staying informed, keeping cool, and staying hydrated, residents can safely navigate this period of extreme heat.
